STILL leaking water! I'm going to scream!

**DNS** · 8th October 2011, 17:26

Had most of the back of my car removed to try and find the cause of this bl**dy leak, but still no luck!

It's NOT:

- aerial (removed, seal chucked out and resealed with silicon)
- quarter window (removed, resealed with silicon)
- rear light cluster (leak is higher up)

Additionally, the leak occurs when the hose is directed well away from these areas.

It's also NOT:

- The rubber gaiter which covers the cables for the tailgate electrics (removed and resealed)
- The mount for the tailgate strut (removed and sealed with PTFE tape)

The water definitely seems to be running down the inside of the D pillar. It's dripping out at the bottom, just above the alarm siren.

Now wondering the seam which is covered by the tailgate rubber seal isn't welded properly. Maybe the old rubber seal (which has been removed and refitted a few times, so not in perfect condition) is causing the water to channel up to the seal and through a hairline gap.

Anyone got any suggestions for me? This is driving me totally and utterly insane now!

Mate, how did you seal up your leak? Going to check if this is the problem by putting a load of tape over the joint, but not sure how to do something more permanent...

Hi i just used clear silicone done the job for me, was going to use tiger seal then just colour match it with a paint pen.

Thanks mate, really hoping this works! I'm driving round with all of the rear interior trim missing and determined not to refit until i've solved the problem!

Know how u feel, i could not belive how much water came through a little crack, spare wheel well was have full after a few hours of rain.

whilst all the trim is off, spray talc powder in certain areas and after soakin car check to see where talc is damp..

It's another of the well known regular issues with Vecs. The rivet/clip that holds the end of the roof rail in place loosens up and water leaks under it. You can buy replacement parts, but usually a bit of silicon round it sorts it out.
